Health Hazards Data
=======================================================
LD50 LC50 Mixture: NOT PROVIDED
Carcinogenicity Inds - NTP: NO
IARC: NO
OSHA: NO
Effects of Exposure: ACUTE: INHALATION?ASPHYXIANT. EFFECTS ARE DUE TO LACK OF
OXYGEN. MAY CAUSE HEADACHE, DROWSINESS, DIZZINESS, EXCITATION, EXCESS
SALIVATION, NAUSEA, VOMITING, UNCONSCIOUSNESS. VAPOR MAY CAUSE INCOORDINA
TION AND ABDOMINAL PAIN. EFFECTS MAY BE DELAYED. LACK OF OXYGEN CAN KILL.
SKIN CONTACT?NO HARM EXPECTED FROM VAPOR. LIQUID (ACETONE) MAY CAUSE
FROSTBITE. SWALLOWING?AN UNLIKELY ROUTE OF EXPOSURE, BUT FROSTBITE OF LIPS
AND MOUTH MAY RESULT FROM CONTACT WITH THE LIQUID. IF SWALLOWED, THE LIQUID
MAY CAUSE NAUSEA. EYE CONTACT?VAPOR CONTAINING ACETONE MAY IRRITATE THE EYES.
LIQUID MAY IRRITATE AND CAUS E FROSTBITE. CHRONIC: NO HARM EXPECTED.
Explanation Of Carcinogenicity: THIS PRODUCT IS NOT LISTED BY NTP, OSHA, OR
IARC.
Signs And Symptions Of Overexposure: NOT PROVIDED
Medical Cond Aggravated By Exposure: THE TOXICOLOGY AND THE PHYSICAL AND
CHEMICAL PROPERTIES OF THIS PRODUCT SUGGEST THAT OVEREXPOSURE IS UNLIKELY TO
AGGRAVATE EXISTING MEDICAL CONDITIONS.
First Aid: INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL
RESPIRATION. IF BREATHING IS DIFFICULT, QUALIFIED PERSONNEL MAY GIVE OXYGEN.
CALL A PHYSICIAN. SKIN CONTACT: IMMEDIATELY WARM FROSTBI TE AREA WITH WARM
WATER NOT TO EXCEED 105?F (41?C). IN CASE OF MASSIVE EXPOSURE, REMOVE
CONTAMINATED CLOTHING WHILE SHOWERING WITH WARM WATER. CALL A PHYSICIAN.
SWALLOWING: DO NOT INDUCE VOMITING. CAL L A PHYSICIAN. EYE CONTACT:
IMMEDIATELY FLUSH THOROUGHLY WITH WARM WATER FOR AT LEAST 15 MINUTES. HOLD
EYELIDS OPEN AND AWAY FROM EYEBALLS. URGENTLY SEEK THE ADVICE OF A PHYSICIAN,
PREFERABLY AN OPHTH ALMOLOGIST.
=======================================================
Handling and Disposal
=======================================================
Spill Release Procedures: DANGER! FLAMMABLE. GAS UNDER PRESSURE. IMMEDIATELY
EVACUATE PERSONNEL. USE SELF-CONTAINED BREATHING APPARATUS. REMOVE SOURCES OF
IGNITION IF WITHOUT RISK. REDUCE VAPORS WITH FINE WATER SPRAY. SHUT OFF FLOW
IF WITHOUT RISK. VENTILATE AREA OR MOVE LEAKING CYLINDER TO WELL-VENTILATED
AREA. FLAMMABLE GAS MAY SPREAD FROM LEAK. BEFORE ENTERING AREA, CHECK
ATMOSPHERE WITH AN APPROPRIATE DEVICE.
Neutralizing Agent: NOT RELEVANT
Waste Disposal Methods: DO NOT ATTEMPT TO DISPOSE OF RESIDUAL OR UNUSED
QUANTITIES. RETURN CYLINDER TO SUPPLIER. DISCARD ANY PRODUCT, RESIDUE,
DISPOSABLE CONTAINER, OR LINER IN AN ENVIRONMENTALLY ACCEPTABLE MANNER, IN
FULL COMPLIANCE WITH FEDERAL, STATE, AND LOCAL REGULATIONS. IF NECESSARY,
CALL YOUR LOCAL SUPPLIER FOR A SSISTANCE.
Handling And Storage Precautions: STORE WITH ADEQUATE VENTILATION. SEPARATE
FROM OXIDIZERS. SECURE CYLINDERS UPRIGHT. SCREW CAP FIRMLY IN PLACE. THERE
MUST BE NO SOURCES OF IGNITION. ALL ELECTRICAL EQUIPMENT MUST BE
EXPLOSION-PROOF. S TORE ONLY WHERE TEMPERATURE WILL NOT EXCEED 125?F (52?C).
STORE FULL AND EMPTY CYLINDERS SEPARATELY.
Other Precautions: PROTECT CYLINDERS FROM DAMAGE. USE A SUITABLE HAND TRUCK.
EQUIPMENT MUST BE NON-SPARKING. NEVER USE COPPER PIPING FOR ACETYLENE
SERVICE. DO NOT OPEN ACETYLENE CYLINDER VALVES MORE THAN 1? TURNS. NEVER USE
ACETYLENE AT PRESSURES EXCEEDING 15 PSIG. OPEN VALVE SLOWLY. IF VALVE IS HARD
TO OPEN, CONTACT YOUR SUPPLIER.

, SMOKING, SPARKS, HEATERS, STATIC DISCHARGE, OR OTHER IGNITION SOURCES AT
LOCATIONS DISTANT FROM PRODUCT HANDLING POINT
=======================================================
Control Measures
=======================================================
Respiratory Protection: USE AIR-PURIFYING OR AIR-SUPPLIED RESPIRATORS, AS
APPROPRIATE, WHERE LOCAL OR GENERAL EXHAUST VENTILATION IS INADEQUATE. AN
AIR-SUPPLIED RESPIRATOR MUST BE USED IN CONFINED SPACES. RESPIRATORY PROTECT
ION MUST CONFORM TO OSHA RULES AS SPECIFIED IN 29 CFR 1910.134.
Ventilation: USE A LOCAL EXHAUST SYSTEM, IF NECESSARY, TO PREVENT OXYGEN
DEFICIENCY AND KEEP HAZARDOUS FUMES AND GASES BELOW APPLICABLE TLVS
Protective Gloves: WORK GLOVES FOR HANDLING; WELDING GLOVES FOR WELDING
Eye Protection: GOGGLES WITH FILTER LENSES SELECTED AS PER ANSI Z49.1/OSHA 29
CFR 1910.33.
